FIG. 1 is a schematic diagram of an application scenario of an embodiment of the present application. The communication system in FIG. 1 may include a network device 10 and a terminal device 20. The network device 10 is configured to provide communication services for the terminal device 20 and access the core network. The terminal device 20 can access the network by searching for synchronization signals, broadcast signals, and the like transmitted by the network device 10, thereby performing communication with the network.

The network in the embodiment of the present application may refer to a Public Land Mobile Network (PLMN) or a Device to Device (D2D) network or a Machine to Machine/Man (M2M) network. Or other networks, FIG. 1 is only a simplified schematic diagram of an example, and other terminal devices may also be included in the network, which are not shown in FIG.

In the 5G New Radio (NR) system, the system bandwidth may reach hundreds of MHz or even several GHz of bandwidth. But when the terminal device is working, it is not always necessary to have such a large bandwidth. For example, at low data rate transmissions, the terminal device only needs to use a smaller operating bandwidth. For This proposes the concept of Bandwidth Part (BWP). After the network device configures the BWP to the terminal device, the terminal device only needs to perform data transmission and reception in the BWP, thereby effectively reducing the power consumption of the terminal device during data rate transmission.

The synchronization channel in the 5G system is transmitted in the form of a Synchronization Signal Block (SS Block). Each SS Block includes a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS). , Physical Broadcast Channel (PBCH) signal, etc. In the LTE system, the PSS, SSS, and PBCH are always located at the central location of the system bandwidth, but the location of the SS Block in the system bandwidth in the 5G system is not fixed, but the network device is flexibly configured according to the deployment requirements. This poses a problem. For example, when a terminal device performs Radio Resource Management (RRM) measurement, signals from different cells, such as SS Block, may be located at different frequency positions, so the terminal device needs to be different at different frequency positions. The signal of the cell is measured. If the different frequency positions where the signals from different cells are located differ greatly in the frequency domain, for example, as shown in FIG. 2, the SS blocks of different cells (eg, cell 1, cell 2, cell 3, cell 4) are respectively located at different frequencies. Location, the terminal needs to adopt a larger receiving bandwidth to receive SS Blocks of all cells at the same time. At this time, the BWP configured for the data transmission by the network device to the terminal device may not meet the requirement for the terminal device to perform RRM measurement.

The embodiments of the present application are based on different requirements of data transmission and RRM measurement by the terminal device, and respectively configure two different bandwidth parts for the terminal device, and the terminal device uses different bandwidth parts when performing different operations, because data transmission and RRM measurement are performed. The bandwidth portion used is different from the bandwidth portion used only for data transmission, so that the terminal device can efficiently perform data transmission in the corresponding bandwidth portion while satisfying the requirements of RRM measurement.

FIG. 3 is a schematic flowchart of a method for data transmission in an embodiment of the present application. The method shown in FIG. 3 can be performed by a terminal device, which can be, for example, the terminal device 20 shown in FIG. 1. As shown in FIG. 3, the data transmission method includes:

At 310, the terminal device determines a first bandwidth portion and a second bandwidth portion.

In 320, the terminal device uses the first bandwidth portion for data transmission and RRM measurement on a specific time domain resource, and uses the second bandwidth portion on other time domain resources except the specific time domain resource. The data is transmitted.

Specifically, the first bandwidth portion (first BWP) and the second bandwidth portion (second BWP) are both bandwidth portions of the terminal device for data transmission, and the first bandwidth portion is also used for terminal design. The RRM measurement is performed, for example, the SS block and/or the reference signal from the cell to be measured is measured, and the reference signal may be, for example, a Channel State Indication Reference Signal (CSI-RS). After the terminal device determines the first bandwidth portion and the second bandwidth portion, the first bandwidth portion can be used for data transmission and RRM measurement on a specific time domain resource, and in a time domain other than the specific time domain resource. Resources, the second bandwidth portion is used for the data transmission.

Optionally, the specific time domain resource includes multiple time domain resources distributed by time period.

Further, optionally, the time period is a time period used by the terminal device to perform the RRM measurement. That is to say, the terminal device can perform RRM measurement according to the time period.

For example, as shown in FIG. 4, the terminal device uses the first bandwidth portion for data transmission and performs RRM measurement on multiple time domain resources distributed according to the time period, and uses the second bandwidth portion for data transmission on other time domain resources. .

Therefore, the terminal device determines two different transmission bandwidths and uses different bandwidth portions when performing different operations, since the bandwidth portion used for data transmission and RRM measurement is different from the bandwidth portion used when only data transmission is performed, thereby The device can efficiently perform data transmission in the corresponding bandwidth portion while satisfying the requirements of RRM measurement.

It should be understood that, in the embodiment of the present application, when the terminal device performs data transmission with the network device on the first bandwidth portion and the second bandwidth portion, the data transmitted may include service data, signaling data, or other types of data, where Not limited. The data transmission may include the terminal device receiving the data sent by the network device or the terminal device transmitting the data to the network device.

In 310, the terminal device determines that the first bandwidth portion and the second bandwidth portion are specifically in the following two manners.

Mode 1

Alternatively, as shown in FIG. 5, 310 may include 311 and 312.

In 311, the terminal device receives the first configuration information and the second configuration information that are sent by the network device.

The first configuration information includes bandwidth information of the first bandwidth portion, and the second configuration information includes bandwidth information of the second bandwidth portion.

In 312, the terminal device determines the first bandwidth portion according to the first configuration information, and determines the second bandwidth portion according to the second configuration information.

Specifically, the first configuration information and the second configuration information are configured by the network device and are indicated to the terminal device by using the first configuration information and the second configuration information. The terminal device receives the first match The information may determine the first bandwidth portion and determine the second bandwidth portion based on the received second configuration information.

Mode 2

Alternatively, as shown in FIG. 6, 310 may include 313 to 315.

In 313, the terminal device receives the second configuration information and the third configuration information that are sent by the network device.

The second configuration information includes bandwidth information of the second bandwidth part, where the third configuration information includes information about a frequency band occupied by at least one signal to be measured by the terminal device in the RRM measurement.

In 314, the terminal device determines the second bandwidth portion according to the second configuration information, and determines a third bandwidth portion according to the third configuration information, where the third bandwidth portion includes a frequency band occupied by the at least one signal.

In 315, the terminal device determines the first bandwidth portion according to the second bandwidth portion and the third bandwidth portion.

Specifically, the network device may send the second configuration information to the terminal device, so that the terminal device determines the second bandwidth portion according to the second configuration information. At the same time, the network device may send the third configuration information to the terminal device, where the third configuration information includes information about a frequency band occupied by at least one signal to be measured by the terminal device in the RRM measurement process, so that the terminal device determines the first information according to the third configuration information. And a third bandwidth portion, the frequency band occupied by the at least one signal should be included in the third bandwidth portion. The at least one signal may include, for example, an SS Block and/or a CSI-RS of at least one cell to be measured by the terminal device. The terminal device will ultimately determine the first bandwidth portion based on the second bandwidth portion and the third bandwidth portion.

Optionally, the first bandwidth portion includes a second bandwidth portion and a third bandwidth portion, and the second bandwidth portion and the third bandwidth portion may at least partially overlap or not overlap.

For example, if the second bandwidth portion is within the third bandwidth portion, ie, the third bandwidth portion includes the second bandwidth portion, the third bandwidth portion may be determined as the first bandwidth portion, such as the bandwidth portion shown in FIG. For example, in the cell 1, the cell 2, the cell 3, and the cell 4, the SS blocks sent by different cells are respectively located in different frequency bands, the third bandwidth portion is a continuous frequency domain resource, and the third bandwidth portion includes the four cells. The frequency band occupied by the transmitted SS block, and the second bandwidth portion configured by the network device for the terminal device for data transmission is located within the range of the third bandwidth portion, the terminal device may determine the third bandwidth portion as the first bandwidth section.

For another example, if the second bandwidth portion does not overlap with the third bandwidth portion, the first bandwidth portion should include at least the second bandwidth portion and the third bandwidth portion, such as the schematic portion of the bandwidth portion shown in FIG. For example, in the cell 1, the cell 2, the cell 3, and the cell 4, the SS blocks sent by different cells are respectively located in different frequency bands, and the second bandwidth portion and the third bandwidth portion do not overlap at all, and the range of the first bandwidth portion is horizontal. The second bandwidth portion and the third bandwidth portion are included in the first bandwidth portion, and the first bandwidth portion includes the second bandwidth portion and the third bandwidth portion, and the first bandwidth portion is a continuous frequency domain resource.

Of course, the first bandwidth portion may also include discontinuous frequency domain resources. For example, the first bandwidth portion may include only the second bandwidth portion and the third bandwidth portion shown in FIG.

The above assumes that the terminal device can acquire information of a frequency band occupied by at least one signal to be measured, so that the terminal device determines the first bandwidth portion according to the third bandwidth portion and the second bandwidth portion. However, if the terminal device cannot accurately obtain the information about the frequency band occupied by the at least one signal to be measured, optionally, the terminal device can use the entire system bandwidth as the first bandwidth portion, so that all the cells to be measured can be guaranteed. The signals are measured efficiently.

Optionally, the foregoing bandwidth information may include at least one of the following: a center frequency, a bandwidth size, and a subcarrier spacing.

For example, the terminal device may determine the center frequency, the bandwidth size, the subcarrier spacing, and the like of the first bandwidth portion according to the bandwidth information of the first bandwidth portion. The terminal device may determine the center frequency, the bandwidth size, the subcarrier spacing, and the like of the second bandwidth portion according to the bandwidth information of the second bandwidth portion.

It should be understood that the bandwidth portion (BWP) in the embodiment of the present application may also be referred to as a transmission bandwidth, a bandwidth segment, a bandwidth configuration, and the like, and a plurality of bandwidth portions may be included in the system bandwidth. Different bandwidth portions may have different bandwidth sizes and/or center frequencies, and the basic parameter sets for data transmission in different bandwidth portions, such as subcarrier spacing, etc., may also be different.

In 920, the network device sends second configuration information to the terminal device, where the second configuration information includes bandwidth information of the second bandwidth portion, so that the terminal device is in addition to the The second bandwidth portion is used for the data transmission on other time domain resources other than the specific time domain resource.

That is to say, the network device can configure different second bandwidth parts for different terminal devices according to deployment requirements, and indicate the second bandwidth part to the terminal device by using the second configuration information. At the same time, the network device may further determine a third bandwidth portion according to a frequency band occupied by the at least one signal sent by the plurality of cells for performing RRM measurement by the terminal device, and finally the network device determines the first according to the second bandwidth portion and the third bandwidth portion. a bandwidth portion, and indicating the first bandwidth portion to the terminal device by using the first configuration information. Alternatively, the network device may not send the first configuration information, but indicate the information about the frequency band occupied by the at least one signal to the terminal device by using the third configuration information, so that the terminal device determines the first according to the third configuration information and the second configuration information. A bandwidth part.

Therefore, the network device configures two different bandwidth parts for the terminal device based on different requirements of the terminal device for data transmission and RRM measurement, so that the terminal device uses different bandwidth portions when performing different operations, because data transmission and RRM measurement are performed. The bandwidth portion used is different from the bandwidth portion used only for data transmission, so that the terminal device can efficiently perform data transmission in the corresponding bandwidth portion while satisfying the requirements of RRM measurement.

It should also be understood that, in various embodiments of the present application, the size of the sequence numbers of the above processes does not mean the order of execution, and the order of execution of each process should be determined by its function and internal logic, and should not be implemented in the present application. The implementation of the examples constitutes any limitation.
